My invention relates to a flashlight of the particular type disclosed in. my copending application for Letters Patent filed October 3, 1928, S rial Number 310,098, and the principal object of mypresentvinvention is to generally improved upon and simplify the construction of the flashlight disclosed in my aforesaid patentapplication, as well as other existing forms of similar flashlights.

Furtherobj ects of my invention are to pro vide a relatively simple, practical and inex pensive flashlight. that is designed to be worn ontlie forehead, thereby enabling the wearer ofthe lamp toutilize both hanc sin manipulating tools or workingon parts that are il luminated by said lamp, further to provide improved means whereby the lamp housing is mounted for universal adjustment upon the baseplate or. supporting member, and

' further to provide a flashlight of the character referred to that comprises relatively few parts that are capable of being readily manufactured, and assembled to produce the complete structure.

With the foregoing and other objects in view, my invention consists in certain novel features of construction and arrangement of parts that will hereinafter be more fully described and claimed and illustrated in the accompanying drawing, in which:

Fig. 1 a vertical section taken through the center of a flashlightconstructed in accordance with my invention.

Fig. 2 is a cross section talienon the line 22 of Fig. 1.

Fig. 3 is a rear clevational view of the flashlight and showing the base plate applied to the forehead of the wearer and which supports the adjustable lamp housing.

Fig. l is a plan View of the flashlight and showing the means for supporting the same on the forehead of the user.

Fig. 5 is a perspective view of a frame that is; utilized for supporting the lamp carrying dish and its socket within the lamp housing.

Referring by numerals to the accompanying drawings which illustrate a practical emhodiment of my invention, 10 designates a plate, preferably formed of thin metal such as aluminum, and which is curved slightly after movement, an expansive spring 15;- is

positioned betvveenthe socket. and member, 14.

Projecting outwardly fromthe center of; the member l lis a threaded studi l tl that serves asa pointof connectionlfor theilamp housing 17. Thislamp housing ispreferably formed of thin; sheet metal, substantially hemi-ovoid in shape and provided on its for! ward end with a thread lSLthat makes one,

complete turn.

Adapted to engage the it thread in the for: Wardenclof the lamp housing is thethreaded portion of a collar or bezehltlthat carries concave reflector 20 and a 1ens2 1 i Arranged within the, rear portion of the, lamp housing 17. is@a,bow-shaped strap or fran1e22 of thin metal, the ends fwhich [are turned inwardly toward each other and se; cured to said ends inany suitable manner is a disk 23 of insulationand theedge thereof fits snuglyagainst the inner face ofthe lamp housing. i

To clamp the frame 22 within. thelamp housing, andto support th e latter ontheladiustable member let, threaded stud l tiprov jects through coinciding openings formed in the lamp housing and frame, and-mounted on the inner end of said stud is a nut 2a.;

Threaded studlti passes throughthelamp housing 17 and frame 22. ata point ashort distance below the axisof thellamp housing, and as a result of this arrangement said hous ing when in its normal position and; Wlthtllfl. plate 10 in proper position up'onfthe forehead, occupies a position slightly abovesaid; plate 10, thereby positioning the lamp within eidheu iee sl ilbsteetie dis nce bove the eyes of the user. Further, such mounting of the lamp housing permits a greater range of adjustability of the lamp housing.

Positioned on the stud between the lamp housing and the member 14 is a spacing collar 25.

Secured to the rear face of disk 23 is a centrally arranged metal disk 26 and formed integral therewith is a threaded'socket 27 that projects; through an opening in the center of disk 28, and said socket receives the threaded plug portion of a small electric.

lamp 28, the bulb of which projects through a centrally arranged opening'in the reflector 20. V I r Secured to the rearface'of the disk 23 is one end of a contact spring 29, the free end thereof occupying a position directly behind the threadedsocket 27 so as to be engaged by the'contact of the plug of lamp 28 when said plug is screwed into the socket 27 V and the lamp housing supported upon said 7 H onto the work that is being done or onto the 7 tools that are being manipulated by the hands dentists, oculists or other Leading from a suitable source of electric current supply, preferably a battery 30, are

oonductorsSl in which is located a suitable switch 32, and one of said conductors is connected to contact spring 29 and the other conductor is connected to the disk 26. V

The. battery 30 and switch 32 are preferably of the type contained in a small house ing or case that may be conveniently carried in the pocket or attached to the clothing of the user of the lamp.

In the use of my improved flashlight plate 10 is positioned on the forehead of the wearerwith the elastic band 12 encircling the head plate 10 may now be shifted into any desired position so as to direct the rays of the lamp of the wearer of the lamp. V

The universal joint between the plate 10 and lamp housing" enables the latter to be easily and quickly swung into various positions and the pressure exerted by the ex pansive spring 15 firmly holds the lamp housmg in its adjusted position.

The frame22 provides a firm and substan{ tial support for the disk 23 thatcarries the.

trouble light while making adjustments and repairs upon automobiles, airplanes, motor boats or'in factany' work that may beac complished to better advantage when illuminated with light rays, and said lamp may also be used to advantage by physicians,

in like professions.

Likewise the lamp may be used by persgns' persons engaged traveling orv driving at night and by persons engaged in mining or other underground Work.

Thus it will be seen that I have provided a flashlight to be worn upon the forehead, thereby enabling the wearer to freely use both hands in the manipulation of tools for accomplishing the various kinds of work, and

which flashlightis relatively simple in con- 'struction', inexpensive of manufacture, and capable'of being easily and quickly adjusted to suit different conditions.

It will be understood that minor changes in the size, form andconstruction of the various parts of my improved flashlight may be made and substituted for those herein shown and described without departing from the spirit of my invention, the scope of which is set forth in the appended claim.

I claim as my invention: a

In flashlight, a plate adapted to be positioned upon the forehead of the wearer, a

socket arranged on the upper central portion of the'front face of said'plate, a'lamp housing, a stud projecting downwardly and rearwardly from the rear portion of said] housingat. a point below the axis thereof, a a

hemispherical member carried by said stud and arranged within-said socket the outer portion of which hemispherical member is provided w th a recess and an expansive spring arranged within said recess and bear ing against said hemispherical member.

In testimony whereof I affix my signature.
